Hi everyone,
I am in the process of determining the most appropriate cryoprobe to purchase
and one of the major driving forces is that of the operation/upkeep costs. I
have a handful of biochemical users, as well as other advanced organic users,
that would greatly benefit from a LHe cryoprobe and personally that is my
preference. However, I was curious to see a few things from others that would
help navigate this decision:
1. What are the yearly costs related to the upkeep of the LHe cryoprobe?
If the cost can be broken down to compare between general upkeep and He costs,
that would be super helpful!
2. I know that is going to depend on usage and operation temperatures, etc.,
but how much LHe do you feel your probe goes through yearly?
3. Is there a way to recover the He boil off from the probe? I am in the
process of installing a He recovery hose to the NMR He stack already, not
sure how that would work to recover from probe (I apologize if this is a silly
question).
Thanks!!!
